WATERFPUMPING'APPARATUS.

SPECIFICATION forming* part Of Letters Patent NO. 676,214, dated June 11, 1901. Application filed November 17, 1900. Serial NoK 36,889. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES ANEsHAENsEL, a citizen of the United States, residing at In.- dianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Tater-Pumping Apparatus, of which the followingr is a spccilication.

My present invention consists, generally speaking, in improvements in that shown and described in my Letters Patent No. 660,239, granted October 23, 1900, and relates to that class of apparatus wherein a water-motor is used for pumping water for household or such like purposes.

As is well known to those familiar with the subject, one great difficulty attending the use of water-motors in pumping water for domestic purposes has been that the motor is kept Acontinuously under pressure from the water which drives it, and this occasions incessant Wear upon the valves of the motor, which rapidly destroys its efficiency. This trouble is aggravated by the fact that for a considerable portion of the time such a motor is driven slowly back and forth by the small amount of Water which passes through it When not 'in Very active operation, at which times, as those familiar with the subject well know,- such sand or grit as may be carried by the water remains in the valves more persistently and cuts said valves more seriously than when it is rapidly Washed through, as when the motor is in full operation. This difficulty was overcome in large measure by the valve apparatus forming the subject-m atter of my said Patent No. 660,239. I have discovered that still better results may be attained by providing means to both regulate the speed of the pump when the same is ,in operation and also to shut off the water from the pump completely, and thus stop its motion altogether except during the time Wateris being drawn for use from the pipes or plumbing system supplied by the pump. Such is the object 0f my present invention, which is accomplished by incorporating in the system an additional valve and somewhat changing the connections, as

will appear from the accompanying description. n

I shall describe my invention as I have applied it in an ordinary household plumbing system, wherein in operation the water which `drives the motor is that usually supplied unsimilar reference characters indicate similar parts, Figure 1 is aside elevation illustrating in a somewhat diagrammatic manner the essential parts of a household water system emjbodying my present invention. Fig. 2 is a central vertical sectional View of the valve which I have added to the system shown in said Patent No. 660,289, with fragments of the pipes connectedthereto; and Fig. 3, a corresponding section of the water-pressurecontrolling valve and which is or may be the same as the valve shown in said patent, although used somewhat diiferently.

I may state, by way of introduction to the detailed description, that the new valve in question occupies a position in the present system which the valve shown in saidkpatent occupied in the system therein described, while the said valve formerly used has been transferred to a point farther out along the line of pipe leading to the pump and by means of different connections has become a pressurecontrollingvalve rather thana shut-off valve to the pump, although in operation it many times shuts off completely, as will hereinafter appear.

Water which operates the motor comes from the mainsorsource of supply through the pipe l1 lb lc to the motor 2, andthe Waste from said motor runs off into the sewer or other place of discharge through the exhaust or waste pipe 3.

The water to be pumped is supplied to the pump-motor through the suction-pipe 4 and is delivered from said pumpmotor to the plumbing fixtures or tank, or both, through the pipe 5, which may or may not have branches, as b, running tovarious points, according to the plumbing system employed. I have shown the main delivery-pipe 5 as running through a check-valve 6 to atank 7, and said tank has a delivery-pipe S and a waste or overflow pipe 9, and to the latter, in a mod- IOO ed. So far the parts are or may be similar" to those illustrated in my said former patent,

and consequently the description is purposely similar.

The pressure-controlling valve is in itself"V similarin construction and arrangement to the valve shown in said PatentNo. 660,239: and is composed of a valve-shell 20, contain; ing a valve-seat 2l, upon which a valve 22 on' the lower end ofthe valve-stein23kis adapt,- edto rest, said Valve-stem being operated in onejdirection by the spring 24, while it is operated in the other direction by the presusre of wat-er coming in from the portion lb of the maiupipe through the by-pass pipe 25 into a chamber above the cup-leather 26, carried by the` valvestem. The cup or piston 26 is of larger diameter than the Valve 22 and is contained within a correspondingly larger chamber in the shell 28, .which is mounted i on the neck of the valve-shell 20, as shown, and the top T ofwhichis removable. The stuffingbox 29 above this chamber, through which the Vvalve-stem 23 passes, is preferably cupsha'ped at/the upper end and is thus well adapted Ito receive a lubricant, as well as the lower end of the spring 24. of-the chamber below the cup 26 has a small vent @communicating with the outer air, in

1 lorder that there shall be no air compression p'edeiuts operation.

within this chamber under said cup to im- The tension of the spring i's regulated by a nut 30.. The tension of the spring 'is Vso'regulated as'to hold the valve open until a certain predetermined pressure is 'reached in that portion la of the pipe outside' the valve 20, when, owing to the larger area of the cup26, the valve 22 will be forced ftoward or against the valve-seat 21. Thus notvvithstanding the variable pressure which may come from the Waterworks or source of supplyv against Vthis Valve an equal pressure inthe pipe inside ,the valve may be always maintained, with the result that the water- Vmotor will be driven at a constant speed when in operation, andthe excessive wear in said motor which takes place where there are un-V equal speeds is thus avoided. As heretofore stated, this lalone is vof considerable advantage in the operation of pumping systems of Athis character. Pressure-controlling valves alone, however, do not -wholly remove pressurefrom the piston of the pump, and this pressure although reduced will cause the slow or creeping motion of the pump above rerferred to, with the result that such a pressurecontrolling valve will from time to time bek fm'otion to pass, with the disadvantages above rspecified. `In order to completely remedy this -rection.

The lower side difficulty, l haveincorporated in this system the Yadditional valve, which will ,now be described. This valve is composed of the shell 40, having the valve-seat 41 and a valve 42 ou the lower end of a valve-stem 43, adapted to rest on said valve-seat. Above the shell 40 (and preferably coupledto said shell by a union u) is a cylinder 44, within which and carried by the valve-stem are two cup-leathers 45and 46 of equaldiameter, one facing in one direction and the other facing in the other di- To the upper end of this cylinder is connected another cylindrical structure 47, (which, however, might be a prolongation of the part 44,) and the top of this is adapted to be closed by a plug or cap 4S, which contains a central vertical perforation into which the upper endof the valve-stem43 extends and which serves as a guide to said stem. Said stem is flattened or grooved onone side,.asat 0c, so

that water may pass freely into and out of the perforation in the cap and the movement of the stem therein not he impeded by suction or friction. To one side of the part 471is connected a small pipe 49, which is a branch leading from one. of `the pipes 5containing the pumped or cistern water. As will be read-l ,ily understood, the cups 45 and 46 Vbeing of the same diameter and respectively adapted to receive pressure coming fromV opposite directions, the Valve itself is an absolutely-balanced valve, so that it is at once opened or closed by any excess of pressure coming from one direction or the other. In this connec- IOO tion itiis to be noted that the water in entering this valve from the pipe-1b enters above the valve-seat instead of, as in ordinary valves, below it,so that there isno pressure on the under side of thev valve when'the same is closed, the pressure being wholly above this lower face of said. valve.'

It is obvious, with the arrangement described, that the pressure inthe pipes ofthe pumped-water system will immediately upon the opening of a faucet be relieved, so that the valve 42 will rise, permitting water to iow through the pipe la lb 1c to the pump-motor and operate the same 4and will immediately after such faucets are all closed increase sufficiently tol close the valve 42 and-shut of the supply of water and stop the `pump-motor. Thus the pu mp-motor can only operate when water vis owing from the plumbing system containing the water which is being pumped,

which, as is well known, is commonly but a small fraction of the time, and therefore under ordinary circumstances the pump is at rest and not being worn by far the greater portionof the time, while it is never subject to operation by leakage and the wearing incident to a slow motion, where the passage of water is not sufficient tofreely wash out sand and grit which may accompany it. In 'other words, .when the valve 42 is closed the water is completely shut off from thep'ump-motor, so that there is no pressure at all upon its piston and no opportunity for wear.

IIO

I-Iaving thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is- Y 1. The combination, in a water-pumping apparatus, of a main pipe leading from a source of water-supply to a watermotor where by water is conveyed under pressure to such motor; said motor; a pressure controlling valve interposed in said pipe whereby pressure of water at the motor is kept regular and constant irrespective of the variations in pressure from the source of supply; a plumbing system` into which water is pumped by said water-motor; a shut-off valve interposed in the pipe leading to the motor betweenthe pressure-controlling valve and said motor and adapted to be opened by the pressure in said pipe, and a connection thereto from the plumbing system into which water is being pumped by the motor `whereby said valve may be closed; the iow of water to said motor being thus permitted when Water is being drawn from the system supplied by the motor and shut off at all other times, substantially as set forth.

2. The combination, in a water-pumping system, of a pressure-controlling valve interposed in the pipe leading to the motor the operation whereof is controlled by a by-pass connecting the upper chamber of said valve to that portion of said pipe inside or beyond said Valve, a shut-off valve interposed in said pipe between said pressure-controlling Valve and said motor the operation whereof is controlled by a pipe leading to the upper chamber thereof from the plumbing system into which water is pumped by said motor, and said plumbing system into which Water is pumped.

3. The combination, in a water-pumping system, of the motor; a pressure-controlling valve in the pipe leading thereto; and a shutchamber above the valve the said valve-shell being so constructed and arranged that the water iiowing to the motor passes into said shell above the valve-seat and thence down through said valve-seat and out to the motor, whereby when said valve is closed no pressure is exerted by the waterwhich operates the motor to keep the Valve open, substantially as set forth.

4. The combination, in a water-pumping system, of the motor, a supply-pipe leading to said motor from a source of Water-supply, a plumbing system into which water is pumped by said motor, a shut-off valve interposed in the supply-pipe, and a branch pipe leading from the plumbing system to the chamber of l said valve, said valve being adapted to be operated in one direction by the pressure in said supply-pipe and adapted to be operated in the other direction by the pressure in the plumbing system through the branchl pipe leading to said valve structure therefrom, and the valve-shell of said shut-off valve being so constructed and arranged that the water flowing to the motor passes in through said shell to above the valve-seat and thence down through saidvalve-seat and out to the motolg.
